This invention relates to pickling apparatus and more particularly to anapparatus for-use, in the lckling of coilsof wire and thelike.

6 The primary object of the invention is to provide an apparatus forefiecting thorough and expeditious pickling of the wire, and morespecifically'to impart a bodily movement to the coils of wire ina curvedpath in the pickling fluid.

A further object of the invention is to provide a pickling apparatus inwhich means is provided for opemngor spreading the convolutions or coilsof the wire during the path, thereby to expose the entire circumferfinesof the wire to the action of the pickling In describing the invention indetail, referonce is herein had to the accompanying drawings, in which-Fig. 1 is a top plan view of the invention;

gig. 2 is a sectlon on the line 22, Fig. 1; an

Fig. 3 is a section on the line 33, Fig. 2.

As shown in the drawings, a pair .of tanks 1 are employed for containingthe pickling fluid, said tanks being mounted in side by side andparallel relation. A pair of'supporting columns 2 are disposed in spacedre ation to one of the ends of the tanks 1, while a similar pair ofspaced supporting columns 3 are 10- cated ad acent to the opposite endsof the tanks 1. The columns 2 are connected by a horizontal girder 4 anda similar-horizontal grider 5 connects the columns 3. Upper and lowerspaced bearings 6 and 7 are connected to the girders 4 and'5 and haveupper and lower horizontal shafts 9 and 8 respectively jourend thereofwhile a similar se ental gear 9 is rigidly secured to each sha 9, andwith the teeth of the two rs intermeshing, .by means of which itwillnoted that the-shafts depending arm 8 rigidly secure bodily movement ofthe coils in a curved.

The wire coil carrie'ris composed naled' therein. Bearings 13 and 14have the,

be rotated in opposite directions. The shaft 8, which is to the left inF' 2 has a thereon. A long link 10 is pivoted. to the lower end of thearm 8" and has its opposite end connected to an eccentric 12 which ismounted on a drive shaft 12. The other shaft 8 has a similar dependingarm 8 aflixed thereto, while a short link 11 is pivoted to the lower endof the arm 8 and is connected to an eccentric 12 also 00 mounted on thedrive shaft 12. The shaft 12 may be driven in any'suitable manner, as,by means of a motor M which is suitably connected thereto as shown inFigs. 1 and 2.

The crank shaft is mounted on a suitable base 12 which latter alsoserves as a support for the motor M. 7

As shown in Figsd l and 2 of the drawings the shafts 8 have;horizontally dispose radial lifting arms 15 connectel thereto, while theupper shafts '9 have corresponding lifting arms 16 afiixed thereto. Itmay be here stated that as many tanks as desired may be employed, andaccordingly the shafts 8 and 9 are equipped with upper and lower pairsof 76 lifting ar so as to provide a pair of such arms at ea h end ofeach tank. The lower lifting arms 15'have vertically disposed yokes 17secured to their outer ends, the outer or free ends of the yokes beingpivoted to the 80 furcations of the arms 15. The arms 15 and 16 aredisposed. direct! over the pickling tanks and confront eac other andhave a wire coil' carrier or holder secured thereto.

of a horizontal bar 18 the ends of which rest in and on the closedbottomsof the yokes 17 as shown in'Fig. 3. The bar 18 is providedadjacent its ends with depending members 19 wardly to the left of isthen moved to a wire coils C. Preferably, theupper face of the member 21is of undulating formation so as to provide seats to receive the innercircumferences of the wire coils to thereby hold the latter againstshifting longitudinally of the member 21, an eye or loop 25 beingsecured to each of the bars 18.

Vertically extending rods 23 are pivoted at 23 to the bifurcated outeror free ends of the arms 16, as shown in Fig. 3. The lower ends of therods 23 project within the tanks 1 and are secured to cradles 24 whichlatter are disposed within the tanks. As shown in Figs. 1 and 3 of thedrawings, the cradles 24 are offset or are disposed to one side of themembers 21.

It will be noted that the cradles are provided withlongitudinallyextending bars 24 which latter are disposed in spaced relation and'inthe formation of a curve the latter corresponding generally to thecurvature of the wire coils.

Referring to Fig. 2 of the drawings, it will be seen that in order toload the carrier, the latter being-disconnected from the apparatus, thefree end of the bar-like member 7 21 is raised and the-member 19-swungout- Fig, 2, which enables the coils C to he moved onto the bar '21.After the coils have been positioned upon the bar'21, the latter and thememberlglt) are whereupon a lifting crane is connected to the-carrier bymeans of the eye 25 thereof and position to lower the carrier so thatthe bar, 18 of the latter is engagedin the yokes 17. Power is thenapplied through the motor M, causing the shafts 8 and 9 to oscillate. inopposite directions,

the medium of the-intermeshing segmental through and 9, thus causing thearms 15,

gears-8 17 and the wire carrier to move the yok downwardly as the arms16 andthe rods 23 together .with rods move upwardly.

' From the foregomg', it will be noted that the wire coils an'd thecradle'are' caused to reciprocate or move toward and away from each Tother and-as they move toward one-another, it
